To identify susceptibility loci for non-Hodgkin lymphoma (NHL) subtypes, we conducted a three-stage genome-wide association study. We identified two variants associated with follicular lymphoma (FL) in 1,465 FL cases/6,958 controls at 6p21.32 (rs10484561, rs7755224, r2=1.0; combined p-values=1.12×10-29, 2.00×10-19), providing further support that MHC genetic variation influences FL susceptibility. Confirmatory evidence of a previously reported association was also found between chronic lymphocytic leukemia/small lymphocytic lymphoma and rs735665 (combined p-value=4.24×10-9).

Understanding patterns of etiologic commonality and heterogeneity for nonHodgkin lymphomas may illuminate lymphomagenesis. We present the first systematic comparison of risks by lymphoma subtype for a broad range of putative risk factors in a population-based case-control study, including diffuse large B-cell (DLBCL; N ‫؍‬ 416), follicular (N ‫؍‬ 318), and marginal zone lymphomas (N ‫؍‬ 106), and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/ SLL; N ‫؍‬ 133). We required at least 2 of 3 analyses to support differences in risk:(1) polytomous logistic regression, (2) homogeneity tests, or (3)

We discuss how cancer affected the employment of almost 800 employed patients who participated in a longitudinal study. The greatest reduction in patients' labor supply (defined as employment and weekly hours worked) was observed 6 months following diagnosis. At 12 and 18 months following diagnosis, many patients returned to work. Based on these and other findings related to patients' employment situations, we suggest 4 areas for future research: 1) collection of employment information in cancer studies; 2) research into racial and ethnic minority patients and employment outcomes; 3) interventions to reduce the effects of cancer and its treatment on employment; and 4) investigations into the influence of employment-contingent health insurance on cancer treatment and recovery.
